Hi @david-osborne_4674, Are you able to pull successfully using npm and ProGet? Also, does your API Key have the Feed API right enabled or if you are impersonating a user, does that user have the ability to publish packages? Also, when you set your NPM auth using: [~]$ npm config set always-auth=true [~]$ npm config set _auth={ENCODEDAPIKEY} Are you base64 encoding your API Key using the format api:{APIKEY}. For example: If my API key is FakeApiKey, I would want to base 64 encode api:FakeApiKey would be YXBpOkZha2VBcGlLZXk=. So the commands to run would be: [~]$ npm config set always-auth=true [~]$ npm config set _auth=YXBpOkZha2VBcGlLZXk= Alternatively, you could use npm adduser to login. Here are some examples: If you ran the command to make ProGet your default repo: npm adduser --always-auth If you are using multiple repos: npm adduser --registry=http://progetrepo/feedname --always-auth If you are using scoped repos: npm adduser --registry=http://progetrepo/feedname --scope=@inedo --always-auth This way uses a username and password. If you want to use an API key, use API as the username as the API Key as the password. Hope this helps! Thanks, Rich
